Research Description FINDINGS AND DISCUSSION

the teacher needed fresh, captivating, and easy-to-operate alternative learning media. 2. Design Stage In designing the video, design of the presentation needed design sketch used to draw media production. The sketch was drawn in a storyboard. It is a design to describe functions used. The storyboard can be seen as follows, but for more detail, see attachment 6. a. Creating assessment instruments of the quality of the video The assessment instruments were questionnaires of product suitability. The questionnaires were assessed by the material expert, media expert, teacher, and students. Assessment instruments of video suitability were taken from assessment instruments by Sungkono. b. Creating assessment instruments of students‟ learning achievement Assessment instruments of video were written tests consisting of 20 question items and 4 options. The questions were taken based on the materials in the video. The questions in pre and posttest were the same. These instruments were approved by the material expert and teacher. The questions and answers of pre and posttest can be seen in attachment 1. c. Creating flowchart The design stage begins with flowchart making as the plot of the researcher‟s thoughts in order to make the development process easier. Flowchart is made to make video designing easier. The scheme of flowchart making can be seen in the following figure. Figure 3.

Designing a product Product design can be seen in attachment 6. e. Arranging materials, question, and answers of the product In this stage, the reasons of material selection were revealed. This topic was chosen, because it was found that this topic was difficult. Material arrangement, questions, and answers were compiled from various references. They are attached in attachment 6. 3. Development Stage a. Making a video The development stage includes producing audio and video, material programming, and supporting component preparation. 1 Producing video and audio The researcher produced a video based on the storyboard and the existing script. The weaknesses are if there were errors in the script, possible mistakes will raise errors in the editing process. 2 Programming materials The produced video and audio were converted into a readable format by all electronic instruments that later would be used to display the video. The format of the video and audio was adjusted with the supporting tools in order to make it easier to use by everyone. As the result, the video is in MP4 format. 3 Preparing supporting components This media development could not be separated from application programs that could support it. In this stage, the components were application programs,
